The purpose of this study was to identify factors related to residential satisfaction, and to examine the rural housing and village environment which enable to derive what should be considered in the future rural housing improvement. Data were collected by questionnaire survey in 11 rural villages - suburban rural area, plain rural area, intermediate rural area, mountainous rural area. The major findings are as follows: 1) The rural residents rather dissatisfied with'management/maintenance','economic value','facade'in housing level, The overall housing satisfaction level was just medium(neither satisfied nordissatisfied). 2) They also dissatisfied with'playground for children','education condition','medical facilities', 'market'in village level. The overa'll village satisfaction level was just above average(slightly satisfied). 3) Vrom the result of ANOVA test, there are no significant differences in residents evaluation for tiousing and village attributes among 4 rural areas. 4) Factor analysis identified six rural housing environmental factors:'inside utilities','housing size' 'aesthetic aspects','safety','privacy','outside utilities'. 5) For the rural village environments six important factors were derived :'public services','commercial convenience facilities','social interaction','environmental pollution','amenity','agricultural service facilities'.

It seems inevitable for residential buildings to be high-rise and allocated near traffic roads due to the overcrowding in urban area. Acoustic environment in those area has been seriously deteriorated by the increase of traffic vehicles. Commonly used sound barriers have a limitation in controlling noise due to diffraction noise of sound barrier. Hence sound barrier is not effective to attenuate noise especially for the residential units in high level. This work aims at evaluating noise reduction according to the tunnel section shape by using 1/5 scale model. We carried out a number of field measurements for 1/5 scale model of Noise Barrier Tunnel with various sectional shape. The results from predictions and the measurement show generally good agreement.

It is common to design the duct branches where to supply the required air flow for individual room in residential apartment house. However it is difficult to adjust the air volume adequately in small air duct branches in residential ventilation system. The purpose of this study is to figure out the performance of Multidrop chamber coupling system for the residential ventilation system. The experiments were designed to simulate apartment of $84m^2$ and established multidrop chamber duct and general duct on the ceiling of the apartment. Distribution performance of air supply rate were evaluated in this experiments. As a result, distribution performance of air supply rate in the general duct is different from designed air supply rate by about 35% ~ 50% and about 10% in the multidrop chamber system. In additional the sound insulation performance of the multidrop chamber system decreased about 20% compared with general duct system. Therefore, the multidrop chamber system is considered to satisfy proper air supply rate of each room and to improve the sound insulation performance in apartment Houses.

The purpose of this study was testing the attitude differences on common space management between expecting residents and residents in high rise mixed-use residential buildings(MURB). Research method was social survey with questionnaire from 176 residents and 67 expecting residents by snow balling sampling. Research results were 1)residents want mostly 'convenience', but expecting residents want mostly 'amenity' from MURB environment 2)residents and expecting residents showed statistically significant attitude differences on willingly to pay, amount to pay and paying method about common spaces & facilities. 3)above two groups showed statistically significant difference on opening the common spaces & facilities to the community. 4)residents showed higher than expecting residents on impact degree of common spaces & facilities to neighborhood intimacy. 5)most of residents and expecting residents had an idea of 1-2 hour per week volunteer service at common spaces & facilities. Conclusively, survey on expecting residents's opinion might be needed to enhance the usability of common spaces and facilities in MURB. After the residents moving in, periodical evaluation about usability of each spaces & facilities needed to remodel common spaces.

Though super-highrise apartment buildings have become increasingly widespread, their negative effects on the residents have not been investigated sufficiently and practically in domestic situations. In particular, the foreign discussion on residential environment and the residents' health can not be applied domestically due to physical or cultural differences including physical residential space structure and life-style. Therefore, this research aims to investigate the inter-relationship between residence in super-highrise apartments and their residents' health, to reveal the problems which exist. for this purpose, a parental-response health evaluation - questionnaire on children's physical, emotional and behavioral characteristics was given to a total of 336 persons. The health of the children living in super-highrise apartments is evaluated to be good, and is related to what floor of the apartment building people live on. It is represented that the higher the story, the better the children's health. However, there is no meaningful difference according to various evaluation items including the frequency and type of disease, emotional health, behavioral characteristics, etc. Therefore, it cannot be said that children's health shows no meaningful differences depending on what floor they live on. The parents dwelling on higher floors of the building display a more careful educational attitude. This is because they feel anxious about the children's safety as shown by the fact they live on higher stories.

This study measured and analyzed the weather characteristics and the air-ion characteristics of walking space by land use type in Chungju, Chungcheongbuk Province during the heat wave. We used the land registration map to classify the type of land use in walking areas in the studied into the production and green area, the residential area, and the commercial area. We then selected 44 measurement points in about 4.1 km. They included 12 walking space points in the green area, 14 in the residential area, and 18 in the commercial area. Moreover, we calculated the ion index by analyzing the impact of weather factors such as temperature, relative humidity, solar radiation, and net radiation in the walking space on the anion generation and cation generation by land use type during the heat wave. Comparison of air ion characteristics in walking space by type of land use during the heat wave showed that the average cation generation was in the order of commercial area ($700.73cations/cm^3$) > residential area ($600.76cations/cm^3$) > green area ($589.73cations/cm^3$). The average anion generation was in the order of green area ($663.95anions/cm^3$) > residential area ($628.48anions/cm^3$) > commercial area ($527.48anions/cm^3$). The average ion index was in the order of green area (1.13) > residential area (1.04) > commercial area (0.75). This study checked the weather characteristics, cation generation, and anion generation in walking space according to the land use type during the heat wave and checked the difference of ion indexes in the walking space according to the land use type. However, there were limitations in the lack of accurate comparison according to the land use due to the moving measurement and the insufficient quantitative comparison according to the change of road width. Therefore, we recommend further studies that consider the road characteristics.

In the COVID-19 crisis, the elderly over 60 have various psychological health problems such as depression, anxiety, and fear, and the community has become the only space for senior activities. To this end, this study presented a therapeutic aging-friendly community environmental design evaluation system using theoretical review, FGI interview, and hierarchical analysis AHP. The evaluation system is a three-dimensional space, with 10 upper layers and 68 lower layers. In addition, the weight of each index of the evaluation system was distributed through expert survey and SPSS program analysis. First, the material space environment design must satisfy the comfort and health of the elderly when they are active in a common space for their daily life. Second, the design of social space environment is designed to promote exchange and social connection among the elderly. Third, the operating space environment design considers the operating system of the community operating company as important. Through this, it is expected to improve the psychological health of the elderly by providing systematic technical basis and action guidelines for the development of the residential environment of the elderly.

This study calculated monthly and sectoral (for industry, energy industry, transport, residential, commercial and public sectors) greenhouse gas (GHG) emissions of Seoul, Korea from 1999 until 2009 with following the IPCC 2006 Guideline for National Greenhouse Gas Inventories through an analysis on available monthly data of fossil fuel and electricity consumption for the period. The time series analysis showed that GHG emissions had significant cyclical pattern season by season with the highest peak in August and the lowest peak in January throughout the period. The analysis on monthly and sectoral energy consumption showed that residential, commercial and public sectors had emitted about 65% of total GHG emissions of Seoul and had consumed more energy in winter for heating. About 30% GHG of Seoul was emitted from transport sector but its monthly energy consumption showed irregular pattern and it consumed 80% petroleum (in 2009) of Seoul. Hopefully together with further study on this subject, it is expected that this study can be used as basic data for various research regarding Greenhouse gas baseline emission, energy consumption pattern and estimation for future GHG emission of Seoul.

The purpose of this study is a proposal about the flexibility of the performance category to revitalize the "Housing Performance Grading Indication System". This system consists of 5 main performance parts, 14 performance categories and 20 detailed performance lists. 5 main performance parts are Noise and Acoustics(Light-weight impact sound control, heavy-weight impact sound control, sound control of toilet, sound control of party wall), Long-life(flexibility, remodeling & maintenance, durability), Landscape & Indoor Environment(landscape, formaldehyde control& ventilation, daylighting, thermal environment), Welfare & Barrier-free(playground and community center, welfare space, barrier-free design), Fire Safety(fire safety, safe place, fire-resisting quality). The flexibility of the performance category is conformed to Long-life housing related grading and can realize the Long-life housing in response to resident needs about the space rearrangement. Now, The flexibility of the performance category is limited to the evaluation of the private space, that is, the Skeleton evaluation. This study would suggest alternatives to improve uppermost limits through analyzing 60 examples from January 9th 2009 to October 30th 2008. The flexibility of the performance category is possible to estimate not only the Skeleton evaluation but also the Infill evaluation in response to social changes.
